SPECIFICATION forming part of Letters Patent No. 309,204, dated December16, 1884.

Application filed February 20, 1884.

To all whom it may concern:

Be it known that I, JAMES HENRY OooKUs, a citizen of the United States,residing at Eagle City, in the county of Hardin and State of Iowa, haveinvented certain new and useful Improvements in Ohurns, of which the following is a specification.

My improvement relates to that. class churns having a vertical tub orbarrel within which the dasher' is given a vertical reciprocation.

The object of my invention is to provide means, first, for the economyof strength in the reciprocation of the dasher; and, second, for themore thorough agitation of the cream, with the result of effecting amore speedy separation of the butter than is possible with any churn nowin use. To this end my improved churn is provided with a tub or barrel,preferably square in cross-section, having rigidly fixed to one side anarm the end of which serves as a fulcrunrpoint for the dasher-operatinglever, which is pivoted at one end to the said-arm and at the center tothe top or any intermediate point of the dasher-staff. The dasher properis made in rectangular form by means of two cross-bars, to which arehinged four valves or wings seated upward against the bottom of thedasher, and opening downward when the dasher is raised, to allow thepassage of the cream. W hen the dasher is depressed, however, the wingsare pressed to their seats, and the cream forced through aperturesformed therefor in the cross-bars.

I11 order that my invention may be more fully understood, I will proceedto describe it with reference to the accompanying drawings, in whichFigure 1 is a vertical sectional view of my improved churn, Fig. 2 is aplan view of the dasher. Fig. 3 is a vertical sectional view of the sameon the line 3 3, Fig. 2.

1 represents the tub or barrel of my improved churn, preferably ofrectangular shape, and supported by short legs 2 2 from the floor.

3 is a rigid arm, fixed to the barrel of the churn at 4: by any suitablemeans, and. extending somewhat above the top of the churn to receive theend of a lever, 5, which is pivoted thereto. To the middle of the saidlever 5 is hinged the dashcr-rod 6, means being thus provided for thereciprocation of said dasherrod through the medium of the lever. The

dasher-rod passes through the slot 7 in the top (No model.)

8 of the churn, such slot being of sufficient length to allow a slighthorizontal vibration to the dasher-rod. To thelow er end of thedasherrod is fixed the dasher proper, made of two cross-bars, 9 10, witha surrounding frame,11, of rectangular form. Four valves orwings,12

bars, and so hung as to open freely down ward, but to be limited intheir upward movement by studs or blocks 14 011 the frame. Instead ofthe arrangement here shown the wings may be pivoted at any other pointbetween the cross-bars and frame, and the posi tion of the studs 14 bechanged accordingly. The cross-bars 9 are apertured vertically at 15'andhorizontally at 16, said apertures 15 16 intersecting at theirmidlength, so as to form a four-way recess in the cross-bars.

It will be seen that the above-described arrangement is such that whenthe dasher is raised the wings or valves will open and allow the freepassage of the cream; but when the dasher is forced down, the valvesclose upwardly against their seats 14, forming a flat surface throughwhich the cream cannot pass, and forcing it, therefore, up through theways in the cross-bars, and thus causing a great agitation of the creamand a consequent speedy separation of the butter.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In combination with a reciprocating dasher-rod, a dasher formed ofcross-bars and wings or valves hinged thereto, said cross-bars beingapertured vertically and also horizontally above said wings or valves,substantially as set forth.

2. In combination with a reciprocating dasherrod, the dasher composed oftwo apertured cross-bars, an encircling frame, and wings or valveshinged thereto, substantially as and for the purpose set forth. 1

3. The reciprocating dasher consisting of crossbars 9 10, havingvertical and horizontal ways, as shown, and wings or valves hinged tothe cross-bars, and adapted to close upwardly against fixed blocks orprojections on the dasher, substantially as set forth.
